WP-A1: Science Requirements and Architecture Definition

The original definition of this position is:

Objectives

To define the science requirements and functional requirements for the AstroGrid project.

This work package will define the overall scope of AstroGrid in sufficient detail that it can be implemented based on the outputs of this work package. It will take the vision as expressed in the submissions to PPARC, gather requirements from the community, and generate documents describing AstroGrid in increasingly refined levels of detail. One objective will be to have a clear statement to the end users of what they can expect from AstroGrid once it is available.

Inputs

Statements on the cost and availability of the technology we expect to use, such as high-speed networks, storage arrays and commercial software. These will be necessary to ensure that there is a reasonable match between the requirements and the cost of meeting them.

Tasks

Hold open meetings to gather requirements from the UK community

Follow up expressions of interest with group visitsDistil the inputs to a coherent and consistent set of requirements

Prioritise the requirements in case not all can be satisfied within the current project

Develop functional requirements from science requirements, i.e. what does AstroGrid need to do, rather than stating the scientific issues
